1 Juniper Unite Cloud-Enabled Enterprise Reference Architecture Achieving agility by simplifying and securing the enterprise network Challenge The enterprise network is no longer just a business necessity. To truly enhance employee productivity, corporations must transform their enterprise networks into agile, secure services platforms that are accessible by users anywhere, anytime. Solution Juniper s Unite Cloud-Enabled Enterprise is a comprehensive reference architecture that allows business organizations to build a secure, high-performance corporate campus/branch network. Benefits Simplifies infrastructure deployment, management, and operations while accelerating service bring-up Secures the enterprise with a suite of solutions that defend everything from the infrastructure to cloud-based services and feeds Integrates partner offerings for WLAN and other key thirdparty components, providing cohesive, best-in-class options for customers The cloud is central to the transformation of the enterprise. From public to private to hybrid, enterprises are adopting cloud technologies as their primary operating model, making campus networks the critical on-ramp to cloud-based applications deployed in private clouds, on-premise data centers, or hosted in remote locations. Network virtualization is also transforming enterprise IT, offering a springboard to the flexibility and agility of the cloud. With virtualization, networks can evolve into new deployment and management paradigms, with enterprise campus and branch networks reaping the benefits of centralized visibility and control. The Challenge The widespread adoption of mobile networking and social media is increasing reliance on cloud-driven applications, which need to be delivered to multiple locations and devices. When combined with BYOD, Internet of Things (IoT), and the increasing sophistication and variability of threats, it s clear that everything connected to or transmitting through the network is a potential security risk. Large public cloud players, and even some private cloud players, have sparked a network transformation with innovations like SDN, Network Functions Virtualization (NFV), automation, analytics, and proactive network assurance designed to create an agile network infrastructure that makes IT a competitive advantage. Enterprise network transformation is about reducing CapEx and OpEx, freeing up budget to invest in revenuegenerating applications that streamline the business, while creating a network foundation that effectively leverages these technology and productivity enablers. Unfortunately, the majority of today s campus networks are manual systems comprised of layers of switches and VLANs, with multiple management points requiring different tools and adding operational complexity. Multiple layers and flavors of security solutions, ranging from load balancers to firewalls, add even more to this complexity. Because these layers of products must be administered manually, the potential for configuration errors that disrupt services or open security gaps increases, making it riskier and more challenging than ever to operate and manage the distributed enterprise. A cloud-enabled enterprise network, on the other hand, enables rapid deployment of new services and increases employee productivity. Providing a common, converged network spanning distributed locations, a cloud-enabled enterprise can recognize and support a diverse set of wired and wireless devices, applications, people, and things, seamlessly and securely connecting them to services. Cloud-enabled enterprise networks make the IT department a service provider for its company s distributed locations, enabling the delivery of reliable, scalable, and secure connectivity that links telecommuters, remote locations, and corporate offices to a common system. 1

2 Juniper Networks delivers a comprehensive cloud-enabled enterprise solution that leverages technology utilized by service providers and mega cloud providers to deliver highscale services capabilities for enterprise IT departments. Using innovations derived from building the world s largest cloudbased networks and applying them to the enterprise, Juniper delivers a simplified, programmable network platform that can be easily customized and replicated across branches, campuses, and on-premise data centers, allowing businesses to deploy their own private or public clouds. The Juniper Networks Unite Cloud-Enabled Enterprise The Juniper Networks Unite Cloud-Enabled Enterprise is based on a three-pronged approach: simplifying the infrastructure; securing the network; and delivering an open, converged framework that ensures best-in-class deployments. Based on Juniper switching and security solutions including unified threat management, next-generation firewalls, and malware detection and eradication tools, as well as best-of-breed WLAN, UCC and network solutions through an Open Convergence Framework Juniper Unite offers all the essentials an expanding business needs to support their operations today while preparing them to embrace the future. Simplify the Infrastructure By collapsing core, distribution, and access layers into a single logical platform that can be managed from a central location, Juniper removes operational headaches while providing network agility. A single, easy-to-manage platform lets IT organizations expand access port functionality, protect the edge, and centralize configuration, provisioning, management, policy, and visibility. It all works regardless of the deployment model: physical or virtual; public or private cloud; or traditional IT. Based on Juniper switching and security solutions including unified threat management, next-generation firewalls, and malware detection and eradication tools Juniper Unite offers all the essentials an expanding business needs to support their operations today while preparing them to embrace the future. Juniper accomplishes this consolidation with Juniper Networks Junos Fusion Enterprise, an innovative architecture that lets customers build an agile enterprise network that treats access switches as extension ports of the core switch effectively making multiple switches appear as a single, logical device. Junos Fusion Enterprise utilizes automated configurations to simplify operations and management; it also supports both stacked and mesh topologies, allowing both end-user access and private cloud or IT data center environments to be consolidated into a single logical system. Securing the Enterprise The Juniper Unite Cloud-Enabled Enterprise also provides comprehensive security and control with Juniper Networks SRX Series Services Gateways and the Junos Space Network Director and Junos Space Security Director applications, which provide network performance monitoring and capacity planning as well as centralized security policy management and control.

3 While there are many ways to detect and isolate intruders and bad actors, technology that requires the replication of an exact environment for the intruder is inferior to other solutions. Creating such an environment including the creation of virtual machines (VMs) and mirroring the operating system and applications where the intruder exists is not only challenging, it doesn t scale well. Simply maintaining such an ecosystem of software compatibility in order to isolate intruders becomes a project in and of itself. A much more effective way to detect and isolate attackers is to immediately segment out intruders or bad actors by quarantining them in a sandbox area. Such technology currently exists, and it is much easier to use existing network capabilities than to create yet another layer of complexity and operational headaches. Juniper provides this visibility and centralized network policy control using an open policy enforcement platform to stop threats faster and more effectively, both from a cost and an efficiency perspective. Juniper Networks Spotlight Secure gathers comprehensive, up-to-date threat and security intelligence and instantly communicates it to Security Director, which in turn sends the information to all SRX Series platforms in the network. Additionally, Juniper Networks Sky Advanced Threat Prevention delivers cloud-based protection and prevents malware from infecting the network by detonating downloads in a cloud sandbox, allowing SRX Series devices to identify and block any malicious threats.
